1.1.5 Deduce the significance of the differences between two sets of data using calculated values for t and the appropriate tables
1.1.6 Explain that the existence of a correlation does not establish causal relationship between two variables
Lesson: t-values & Correlation
What are "t-values"
t-values are for determining differences between two "things:"
traits in two groups (men & women's heights)
